    Tungsten trioxide (WO3) is a widely studied material for electrochromic applications. The structure, morphology and optical properties of WO3 thin films, grown by matrix assisted pulsed laser evaporation (MAPLE) from monoclinic WO3 nano-sized particles, were investigate...

    The paper describes the construction of a Bulgarian-English treebank aligned on the word and semantic level. We consider the manual word level alignment easier and more reliable than the manual alignment on syntactic and semantic level. Thus, after manual word level ali...

    Popular metrics used for evaluating image captioning systems, such as BLEU and CIDEr, provide a single score to gauge the system’s overall effectiveness. This score is often not informative enough to indicate what specific errors are made by a given system. In this stud...

    Browsing the biographies of the generation of Bulgarian teachers who lived and worked in the years around the liberation-bringing Russo-Turkish war (1877--1878), we see the clear outlines of the impediments blocking the education and development endeavors of the young B...

    We present a 3D model of a surface-wave-sustained discharge at 2.45 GHz at atmospheric pressure. A small plasma source creates a plasma column in a dielectric tube and a plasma torch is observed above the top. The plasma parameters and the axial profile of the gas tempe...
